Abstract (en)
[origin: WO2018203288A1] A hydraulic connecting unit (10), in particular for cooling and heating plants, has a one piece body (11) in which two respective communicating hollow ball shutters (16, 36) are received, which are provided with different flow paths (17, 17', 18, 37, 38), which are actuated from the outside by levers (23, 39) to be rotated to a plurality of positions to allow various operating conditions of the hydraulic unit. A hydraulic unit is thus obtained which is easy to assemble, highly fluidtight and dimensionally small.
